Figure. Operational Schematic Specifications Specifications for a given construction as it originally comes from the factory are stamped on the main valve and pilot nameplates. The main valve nameplate is located on the main valve body. The pilot outlet pressure range appears on the pilot nameplate. Principle of Operation As long as inlet pressure remains below set pressure, the pilot control spring keeps the pilot valve plug closed (Figure ). This pressure provides the loading pressure to help the main valve spring keep the main valve plug tightly shutoff. An inlet pressure rise above the set pressure overcomes the pilot control spring and opens the pilot valve plug. Loading pressure bleeds out the pilot exhaust faster than it can be replaced through the pilot restriction. This permits inlet pressure to unbalance the main valve plug and open the main valve. As inlet pressure drops back to set pressure, the pilot control spring closes the pilot valve plug. Loading pressure again builds up to close the main valve plug. Installation! WARNING Personal injury, equipment damage, or leakage due to escaping gas (or liquid) or bursting of pressure-containing parts may result if the relief valve is installed where its capabilities can be exceeded 3

To avoid this, install a Type 63EG-98HM relief valve where: Service conditions are within unit capabilities (including those given in the Specifications section). Service conditions are within applicable codes, regulations, or standards. Additionally, physical damage to the relief valve could break the pilot off the main valve, causing personal injury and property damage due to escaping gas (or liquid). To avoid such injury or damage, install the unit in a safe location. 1. Use qualified personnel when installing, operating, and maintaining relief valves and backpressure regulators. Before installing, inspect the main valve, pilot, and tubing for any shipment damage or foreign material that may have collected during crating and shipment. Make certain the body interior is clean and the pipelines are free of foreign material. Apply pipe compound only to the external pipe threads with an NPT body, or use suitable line gaskets and good bolting practices with a flanged body.. A Type 63EG-98HM may be installed in any orientation, as long as flow through the valve matches the direction of the arrow on the main valve body.! WARNING Type 63EG relief valves vent from the main valve outlet and from the pilot exhaust. In hazardous or flammable gas service, personal injury, death, or property damage may occur due to fire or explosion or exposure of vented gas (or liquid) that has accumulated. To prevent such injury or damage, provide piping or tubing to vent the gas (or liquid) to a safe location. The exhaust piping must be designed and installed to guard against excessive flow restriction. This piping must be protected against condensation or anything else that could clog it. For safety during shutdown, vent valves are required immediately upstream and downstream of the main valve on a backpressure or bypass installation. 4

3. If system operation is necessary during maintenance or inspection, install isolating and vent valves as needed. 4. A relief valve must be installed so that the pilot exhausts properly and in a safe place. Make sure to keep the pilot spring case vent open to atmospheric pressure. 5. If the exhaust is to be piped to the main valve outlet or remotely vented, install obstructionfree tubing or piping with a minimum number of bends into the 1/ NPT pilot exhaust connection. 6. If using pipe, apply a good grade of pipe compound to the external pipe threads before making the connection. Install tubing or piping into the appropriate pilot connection. 7. Set pressure is defined as the pressure at which the pilot starts to discharge. The set pressure of a unit is adjusted by changing the control spring compression on the pilot, by using the adjusting screw. 8. Each pilot is factory set for the relief set pressure specified on the order. If no setting is specified, set pressure is factory set at the midrange of the pilot control spring. Startup and Adjustment Key numbers are referenced in Figures 4, 5, and 6 unless otherwise indicated. 1. With proper installation and adjustment completed, slowly open the upstream shutoff valve while using gauges to monitor pressure. On backpressure or bypass applications using an isolating bypass, also open the downstream shutoff valve, and close the bypass valve.. If set pressure adjustment is necessary, monitor inlet pressure with a gauge during the adjustment procedure. Pilot Adjustment Adjust the set pressure by loosening the pilot jam nut (key 17), and turning the pilot adjusting screw (key 15) clockwise to increase or counterclockwise to decrease the set pressure. When the required set pressure is maintained for several minutes, tighten the jam nut to lock the adjusting screw in position. Shutdown Relief Installations Slowly close the upstream shutoff valve. Release all pressure from the main valve and pilot by opening the upstream vent valve. Backpressure or Bypass Installations Slowly close the upstream shutoff valve while opening the bypass valve if an isolating bypass is used. Then close the downstream shutoff valve, and open both vent valves to release all pressure from the main valve and pilot. Maintenance Relief valve and backpressure regulator parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection and replacement of parts depends upon the severity of service conditions or the requirements of local, state, and federal regulations. Due to the care Fisher takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Fisher. All O-rings, gaskets, and seals should be lightly lubricated with a good grade of general purpose grease and installed gently rather than forced into position. Be certain that the nameplates are updated to accurately indicate any field changes in equipment, materials, service conditions, or pressure settings.! WARNING To avoid personal injury and equipment damage, isolate the valve from all pressure. Cautiously release pressure from the valve before attempting disassembly. Type 63EG Main Valve Replacing Trim Parts Perform this procedure if inspecting, cleaning, or replacing individual parts in the trim package. Key numbers for the Type 63EG main valve are referenced in Figures 4 and 5. 5

Easy Trim Maintenance Note Access to the spring (key 9) or flange O-ring (key 1) in step 1 can be gained without removing the body flange (key ). 1. Remove the pilot and pilot pipe nipple from the valve body. Remove the body flange plug (key 7) and the spring (key 9) and attached parts. Proceed to step 5 if only performing maintenance on these parts.. Remove the cap screws (key 3) and pry the body flange (key ) loose from the valve body (key 1). 3. The valve body (key 1) can be used as a holding fixture by flipping the body flange over, and anchor it on the valve body as shown in Figure 3. 4. To gain access to the port seal (key 1), upper seal (key 15), or valve plug parts, unscrew the seat ring (key 13) from the cage (key 11) and the cage from the body flange (key ). For leverage, a wrench handle or similar tool may be inserted into the orifice slots (Figure 3) and a strap wrench may be wrapped around the cage, or a soft bar may be inserted through the windows of a standard cage. To remove the piston ring (key 14) and/or plug O-ring (key 0), remove the valve plug (key 16) from the body flange, insert a screw-driver into the pre-cut fold over area of the piston ring, and unfold the piston ring. 5. Replace parts such as the gasket (key 4) and cage O-ring (key 17) if worn or damaged, making sure that if the port seal (key 1) and upper seal (key 15) were removed they are installed in their retaining slots with the grooved sides facing out. Lightly lubricate seating surfaces and parts as necessary for ease of installation. For proper operation, a Type 63EG valve plug must have pipe plugs (key 31) installed in all four balancing ports. 6. Install the plug O-ring (key 0) and piston ring (key 14) onto the valve plug (key 16). Insert the valve plug into the body flange (key ), install the cage (key 11) plus upper seal (key 15) and cage O-ring (key 17) into the body flange, and then install the seat ring (key 13) plus port seal (key 1) into the cage. Use the valve body as a holding fixture during this step as shown in Figure 3, and insert a wrench handle or similar tool into the orifice slots for leverage when tightening the orifice and cage. Note When installing the trim package, align the body flange and valve body side tappings. 7. Remove the upside-down body flange (key ) if it was anchored on the body. Lightly lubricate the cage seating surfaces of the valve body web and the body flange. Install the body flange on the body (key 1), and secure it evenly with the cap screws or stud bolts (key 3). Install the pilot and its pipe nipple, and connect the pilot tubing. 8. Install the spring (key 9), and place the flange O-ring (key 1) on the flange plug (key 7). Install the flange plug; if necessary, compress the spring enough to ensure secure engagement of plug and body flange threads before final tightening of the plug. Type 98HM Pilot The following instructions explain the disassembly of the Type 98HM relief or backpressure pilot. Sparingly apply a good grade of light grease when reassembling. Key numbers are referenced in Figure 7. 6

1. Loosen the jam nut (key 17) and turn the adjusting screw (key 15) counterclockwise to relieve the spring tension. Remove the cap screws (key 16). Lift off the spring case (key ), spring (key 11), and upper spring seat (key 9).. Lift out the diaphragm assembly, including pusher post (key 6), lower spring seat (key 8), diaphragm (key 1), washer (key 7, not shown), and valve plug (key 4). When using or metal diaphragms, two diaphragms are required. Replace valve plug sealing O-ring (key 53), if damaged or worn. Note If there is severe damage to the seating surfaces, replace the orifice and valve plug O-ring with new parts. However, if only slightly worn or scratched, it is possible to repair metal seats by using the following lapping procedure. 3. Lapping procedure: a. Apply a small amount of 500-grit silicon carbide or aluminum oxide lapping compound on a flat surface such as a piece of heavy plate glass. b. Place the part in the compound and move it in a Figure 7 motion. Do not tip or rock the part since this would round the corners. c. Repeat step b for each part, using an 800-grit or 1000-grit silicon carbide or aluminum oxide lapping compound. d. Wash away all traces of the lapping compound. To help prevent scratching the seating surfaces, apply a light coat of oil before placing the valve plug and orifice in the body. 4. Place the seat ring (key 3) and valve plug (key 5) guide in the body. 5. To replace the valve plug O-ring (key ), remove the machine screw (key 4), and O-ring retainer (key 1) from the valve plug (key 4). Remove and replace the valve plug O-ring. 6. Separate the remainder of the diaphragm assembly parts. Take the locknut (key 6) off of the pusher post (key 6). Slide off the washer (key 3), lower spring seat (key 8), diaphragm(s) (key 1), washer (key 7, not shown), and gasket (key 10). 7. Slip the valve plug (key 4) onto the pusher post (key 6). Note If changing the diaphragm material, a new pusher post is required. Each diaphragm material requires a different length pusher post. 8. Check the diaphragm gasket (key 19) for damage and replace it if necessary. 9. Slip gasket (key 10), washer (key 7, not shown), diaphragms - concave side toward the pressure side (key 1), lower spring seat (key 8), and washer (key 3) on the pusher post (key 6). Screw on the locknut (key 6) and return the unit to the body (key 1). 10. Place the spring (key 11) in the lower spring seat (key 8) and set the upper spring seat (key 9) on the spring. 11. Put the spring case (key ) over the spring (key 11) and onto the body (key 1). Tighten the cap screws (key 16) finger-tight only. 1. Turn the adjusting screw (key 15) clockwise to apply some compression to the spring (key 11). This will ensure proper slack in the diaphragm (key 1). Finish tightening the cap screws (key 16).
